Doctors tested a patient and found that his cells contained normal levels of oxygen and glucose molecules, and no starch molecules. Will this patient be able to exercise normally?

• Yes, the glucose and oxygen molecules can react together to release energy for the body to function.

• No, his digestive system is not breaking down food molecules; his cells need starch molecules to react with glucose, which releases energy.

• No, his body systems are working, but he needs to eat different food; in cells, only amino acids can react with oxygen to release energy.

• Yes, as long as his cells have glucose, they don’t need anything else to release energy for the body to function.
